Why the best frontend app development developers use React and Next.js
We choose React and Next.js for 80% of our projects because they deliver fast, SEO-friendly apps.
React's component model lets us build reusable UI elements that keep code clean and maintainable. Next.js adds server-side rendering, which improves page load times by 40% on average. We also use TypeScript for type safety and fewer runtime errors.
For real-time features, we integrate Socket.io or Firebase. For state management, we use Redux Toolkit or Zustand. Every project includes automated testing with Cypress and Jest to catch bugs before deployment.
The difference between hiring a freelancer and the best frontend app development developers
IRPR delivers production-ready frontend apps with full ownership and ongoing support.
Freelancers often disappear mid-project or deliver code that does not scale. IRPR assigns a senior frontend engineer who stays through launch and beyond. We use Git-based workflows, code reviews, and CI/CD pipelines so you get reliable, maintainable code.
Every project includes a Roadmap phase (week 2) where we define scope, tech stack, and timeline. You get a fixed price quote before any development starts. No surprises, no delays.
- Hourly billing that rewards slow work
- Junior developers learning on your project
- No design system or component library
- Unclear timelines and scope creep
- No automated testing or CI/CD
- Code ownership often disputed
- Fixed price from the Roadmap phase
- Senior engineers with 10+ years experience
- Custom component library built in Storybook
- Clear 8-12 week timeline with milestones
- Cypress + Jest testing, GitHub Actions CI/CD
- Full source code ownership from day one
How we build your frontend app in 4 phases
From idea to launch, we follow a structured process that keeps you informed and in control.
Phase 1 is the Idea workshop where we map user flows and wireframes. Phase 2 is the Roadmap where we define the tech stack and give you a fixed price. Phase 3 is Product where we build and test in two-week sprints. Phase 4 is Release where we deploy and monitor.
You get a demo at the end of each sprint. You can test, give feedback, and see progress. No black boxes, no surprises.
What ships with every frontend app project
You get more than just code. Every delivery includes everything needed to run and grow your app.
We hand over the complete source code in your private GitHub repo. You also get a CI/CD pipeline on GitHub Actions, automated tests, and a deployment guide. No dependencies on IRPR to maintain the app.
Every project includes a component library in Storybook, so your team can reuse UI elements across future features. We also set up error tracking with Sentry and performance monitoring with Lighthouse.
